Unattractive ?

My husband and I have been married for 4 years and we’re best friends for 2 years beforehand. We have 3 kids together and I think the spark is dying tbh. He’s never once since I got pregnant with our oldest called me sexy or hot. It’s always “cute”. He turned to porn for a while and looked up big boob and big butt women behind my back. I figured it out every time and always told him I’m tired of him neglecting me and sneaking around with it. Well he finally stopped doing that but has shown that he’s interested in bigger woman. I’m a petite girl with size DDD bra size but no butt. I’m saggy in all the wrong places and look like I’ve had a few kids 😣 my question here tho is this, he looks at women bigger than me and thinks that’s hot and sexy but I keep telling him I want a breast augmentation and butt botox injections done and he is not having it. I don’t understand. If he finds thicker assets attractive but doesnt want me to get them done does he just want me to be unattractive to him forever?
